Let's divide 78657285 by 838
We're looking to find how many times 838 goes into 78657285.

On to step 1:
The number 838 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 838

On to step 2:
838 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 838

Advancing to step 3:
If we divide 786 by 838, we get 0 and a remainder of 786.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 786 leaves us with 786.
Fetch the next digit (5) from the dividend, attach it to 786 and continue: 7865 / 838

Let's proceed to step 4:
838 goes into 7865 9 times with a remainder of 323.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 323 after subtracting 7542 from 7865.
Take the next digit (7) from the dividend and append it to 323, then repeat: 3237 / 838

On to step 5:
When dividing 3237 by 838, we get 3 with a remainder of 723.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Subtracting 2514 from 3237 leaves us with 723.
Take the next digit (2) from the dividend and append it to 723, then repeat: 7232 / 838

Going ahead to step 6:
When dividing 7232 by 838, we get 8 with a remainder of 528.
Put 8 as the next digit of the answer. 
Result so far: 938.0
Deduct 6704 from 7232 and we're left with 528.
Bring next digit (8) of the dividend behind the 528 and repeat the process: 5288 / 838

Moving on to step 7:
When dividing 5288 by 838, we get 6 with a remainder of 260.
Put 6 as the next digit of the answer. 
Result so far: 9386.0
Subtract 5028 from 5288 to get 260.
Append the next digit (5) from the dividend to 260 and continue with: 2605 / 838

Step 8:
The number 838 fits into 2605 3 times, leaving a remainder of 91.
Use 3 as the next digit of our solution. 
Result so far: 93863.0
The remainder is 91 after subtracting 2514 from 2605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 9:
838 can be fit into 910 1 times, resulting in a remainder of 72.
The next digit of our result is 1. 
Result so far: 93863.1
The remainder is 72 after subtracting 838 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
If we divide 720 by 838, we get 0 and a remainder of 720.
The number 0 becomes the next digit in our result. 
Result so far: 93863.1
Deduct 0 from 720 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 11:
838 goes into 7200 8 times with a remainder of 496.
Use 8 as the next digit of our solution. 
Result so far: 93863.108
If we subtract 6704 from 7200, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 12:
4960 divided by 838 is 5 with a remainder of 770.
Record the quotient 5 as the next digit in the result. 
Result so far: 93863.1085
If we subtract 4190 from 4960, we get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Let's proceed to step 13:
838 can be fit into 7700 9 times, resulting in a remainder of 158.
The number 9 becomes the next digit in our result. 
Result so far: 93863.10859
Subtract 7542 from 7700 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 14:
838 can be fit into 1580 1 times, resulting in a remainder of 742.
The next digit of our result is 1. 
Result so far: 93863.108591
The remainder is 742 after subtracting 838 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

On to step 15:
838 can be fit into 7420 8 times, resulting in a remainder of 716.
Put 8 as the next digit of the answer. 
Result so far: 93863.1085918
The remainder is 716 after subtracting 6704 from 7420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Going ahead to step 16:
838 can be fit into 7160 8 times, resulting in a remainder of 456.
Write down 8 as next digit of the result. 
Result so far: 93863.10859188
Deduct 6704 from 7160 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

The final outcome is 93863.10859188, with a leftover of 4.56e-07.
